The Macomb County Prosecutor’s Office dramatically increased their case Thursday against two men accused of using Facebook to threaten police.

Jailed suspects Brandon Michael Davis, 20, and Richard William Walker, 18, entered 37th District Court accused of malicious use of a telecommunication device — a 6-month misdemeanor — plus felony charges of possession of a short-barrel shotgun, and resisting and obstructing police. The latter counts are 5-year and 2-year felonies, respectively.

The prosecution then dismissed the misdemeanor and charged the two men with false report or threat of terrorism, and using a computer to commit a felony. Both offenses are punishable by up to 20 years in prison.

A Facebook post attributed by officials to Davis states: “We really need more cop killers like for real f*** the cops f*** the court system.”

Comments linked to Walker include: “Wish people would kill more cops we need to have more cops getting killed we need tru (sic) soldiers.”

Photos from the respective pages on Facebook show two men brandishing what appear to be assault rifles and wearing ski masks and gas masks. In a separate photo, a shirtless man believed to be Walker flexes his left arm with the words “cop killer” on his left bicep.

Investigators noted that Warren police had impounded a vehicle driven by Walker a few days earlier.

The Warren Police Department concluded the statements were not random or vague threats, and officials placed the city’s officers on heightened alert.

After obtaining arrest warrants for the two men, Warren police raided Walker’s home on Ford Avenue, near Van Dyke and Nine Mile Road, on Jan. 18. Davis recently began residing there.

Davis hid in the attic and punched and kicked at officers as they tried to arrest him last month, police said. Walker was arrested after a chase and also struggled with officers, police said.

Inside the home, officials confiscated three rifles, two shotguns, a handgun and cases of ammunition, Detective Cpl. Charles Rushton told Judge Matthew Sabaugh. A crossbow, a mini-cannon and pepper spray also were confiscated from the house, police told The Macomb Daily on Wednesday.

Police also seized fireworks with an estimated total value of $10,000.

On Thursday, Walker unsuccessfully asked Judge Sabaugh to release him on a tether.

But as the judge mulled bail, Rushton said: “If he’s willing to kill a police officer, I believe he’s a danger to society.”

Sabaugh increased the bond for Davis and Walker to $500,000 cash or surety.

Both defendants waived their right to have a probable-cause hearing on the terrorism and computer-crime charges held within 14 days. They are scheduled to return to district court Feb. 28 to determine whether they should stand trial on all four charges.

The reason for the more severe criminal charges was not immediately clear. Brian Surma, the assistant prosecutor on the case, told reporters outside the courtroom that he could not comment.

The Macomb Daily attempted to reach Macomb County Prosecutor Eric Smith and his chief of operations, James Langtry, but phone calls to both were not immediately returned.

Davis’ attorney on the initial charges, Warren McAlpine, and Walker’s lawyer, Brian Selburn, declined to comment on the allegations. Both could likely be appointed at public expense to also represent the Warren men on the more severe charges.
